TO'sAID JOSEPH F. "JOsET IMPRovEMENT VINv PAPER-BAG MACHINES.

Specification forming part of Letters Patent No. 173,019, dated February1,'1876; application filed March 31, 1875.

To all 'whom t mag/concern:

Be it known that we,JosE1 HlF. JosE'r'r and JOsIAH Ross, both of thecity of Bualo,`

in the county of Erie and State of New York, have invented certain newand useful Improvements lin Paper-Bag Machines, of which the.

' clearly hereinafter shown.

The second part of our invention consists in the combination of avertically adjustable roller head or frame with the severing device andan adjustable gear-wheel, so that rollers of various sizes may be used.

The third part of our invention consists in the combination ot' thecreasing-rollers and creasing-wheels, when inade adjustable horizontallyand vertically.

The fourth part of our invention consists of an adjustableforming-roller, made adjustable in the direction of its length, so as toanswer for bags of different widths.

In the accompanyingdrawings, Figure l represents a side elevation of the.machine complete; Fig. 2, a plan or top view of the same; Fig. 3, aside view of the severing-rollers, and Fig. 4 an end view.

A represents the frame 'of the machine; B, the paper-roll and roll ofpaper; C, the creasing-roller, over which the paper passes beneaththecreasing-wheels D, which are made adjustable vertically, or nearlyso, by means of the thumb screws and springs d, and horizontally on theshaft by means of the set-screws d'. E represents the adjustableforming-roller. It is made in two parts, one part consisting of acylinder having a portion of smaller diameter, so as to allow the otherportion-a sleeve or barrel-to slide over it'like the tubes of atelescope, so that its length may be increased or shortened. It isadjusted and held when set to the length desired by meansof the bolt orset-screw f. f1 represents the arms for holding it to the shaft f2, uponwhich they are adjusted .horizontally bythe set-screwsff. The arms flare arranged so as to slide in -the parts f4, .and allow the pressure ofthe'roller on the paper to be regulated by means ofthe slots andset-screws g. G represents the two friction rollers. They are heldwithin the frame g1, which is fastened by set-screws g2 to the supportsg3, so that the frame g1 may be e.

made to incline atan angle, more or less, from the horizontal line ofthe machine-bed, and thereby regulate the friction upon the paper as itis drawn through it by th'efeed-rollers H. i h is a set-screw forregulating th'e pressure of said rollers.v The feed-rollers are gearedwith the severing-rollers by means ofthe gearing T, U, V, W,a'nd X. Iand J are the severing-rollers. The lower one is set back of the upper,lone, as shown, so that the paper will lie close to it while the cuttingdevice is separating it. K K are set-screws for regulatin g the distanceof the severing-rollers from each other, and, consequently, theirpressure on the paper. The upper roller I is provided with a serratedbar, '13. j on roller J is a groove,

intov which the bar i strikes when dividing the paper. The point atvwhich the bar t shall enter the Agroove j is regulated by the arm L,which is keyed rigidly to the shaft of roller I. The wheel X, beingarranged to turn easily on said shaft, allows it to be connected to thearm L by means of a set-screw, M, passing through the slotm in saidwheel, by which operation it is obvious the said adjustment may be made.N represents the verticallyadjustable frame for supporting theseveringrollers. It is connected to the frame A by the slide P, and isadjusted by the thumb-screw R. (Shown in dotted lines, Fig.l.) Theobject of the frame N is to allow the use of rollers of different sizes.For large rollers its position would be lower than for small rollers.The wheel V is made movable, so that it can be adjusted and put intogear with the other wheels, so as to connect all together, when theposition of the frame N is changed.

What we claim as our invention is as follows:

1. The combination of the rollers I J, arm L, 4. The forming-roller E,consisting ot' three set-screw M, and wheel X, arranged substanparts-acylinder, sleeve, and setscreW,f-al1 tially as and for the purposedescribed. combined and arranged substantially as and 2.
